I have a page that display some data. It is loaded from a database using php and mysql, I use zend framework to handle all this.
On this page I have two things that use jquery. one is a paginator and the other is a thumps up function.
the paginator works fine. It receives the data as json and applys it to the view. all the functions that I need to handle this are located in one js file. In this file I listen for clicks...
$(document).ready(function() {
$("a#next").click(getProgramms);
$("a#previous").click(getProgramms);
$("a#page").each(function() {
$(this).click(getProgramms);
});
});
Now I have a problem with the thumps up function. It is located in another js file. Everytime the thumbs up button is clicked the script should just alert "click". actually when you click before you use the paginator a "click" appears, but when you do it after nothing happens. but the html in the dom inspector appears to be the same.
in my thumpsup.js I just have
$(document).ready(function() {
$("a.tp").click(thumpsUp);
});
function thumpsUp() {
alert("click");
}
I do not know where the problem is. maybe the js files are interferring each other!?
function thumpsUp() {
var url = window.location.hostname + '/programme/thumpsup/id/'
+ $(this).attr('page');
$.post(url, {
"format" : "json"
}, function(data) {
alert(data);
}, 'html');
return false;
}
I'm guessing the paginator is rewriting your elements and they are losing their click event binding. Try using live() for event binding instead:
$(document).ready(function() {
$("a.tp").live('click',thumpsUp);
});
function thumpsUp() {
alert("click");
}
You might have the Script files (which are included in your mark up) the wrong way round. That's the only solution I can think of...
I'm pretty sure you can get away with two $(document).ready()'s (even if it is frowned upon).

I have a simple jquery script that changes the url path of the images. The only problem is the doesn't apply after I click the load more button. So I'm trying to do a workaround where it calls the script again after clicking the button.
<script type='text/javascript'>
$(document).ready(function ReplaceImage() {
$(".galleryItem img").each(function() {
$(this).attr("src", function(a, b) {
return b.replace("s72-c", "s300")
})
})
});
</script>
HTML
Load More
While Keith's answer will get you what you are looking for, I really can't recommend that approach. You are much better off with something like this.
<script type="text/javascript">
$(function() {
var replaceImage = function() {
$('.galleryItem img').each(function() {
$(this).attr('src', function(index, value) {
return value.replace('s72-c', 's300');
});
});
};
replaceImage();
$('.js-replace-image').on('click', replaceImage);
});
</script>
Using this html
<button class="js-replace-image">Load More</button>
By taking this approach, you do not expose any global variables onto the window object, which can be a point of issue if you work with other libraries (or developers) that don't manage their globals well.
Also, by moving to a class name and binding an event handler to the DOM node via JavaScript, you future proof yourself much more. Also allows yourself to easily add this functionality to more buttons very easily but just adding a class to it.
I updated the anchor tag to a button because of the semantics of what you need to do - it doesn't link out anywhere, it's just dynamic functionality on the page. This is what buttons are best served for.
I'd also recommend putting this in the footer of your site, because then, depending on your situation, you will already have the images updated properly without having to click the button. The only need for the button would be if you are dynamically inserting more images on the page after load, or if this script was in the head of your document (meaning jQuery couldn't know about the images yet).
I hope this helps, reach out if you have questions.
I have a div within a cshtml file that shows the view from another action, as follows:
<div id="tabs-1ua">
#Html.Action("Index", "Admin")
</div>
This loads fine on initial page load. In a separate js file, I have an event catcher for the div as follows:
$("a[href='#tabs-1ua']").click(function (event, ui) {
$("#tabs-1ua").val("#Html.Action('Index', 'Admin')");
});
As can be seen above, the val parameter is the same Razor code that appears in the original div. However, this doesn't get me the desired outcome of the action being performed each time that div event is activated. What is the correct way to activate the razor code each time the event occurs? I made sure the event is captured by testing with alerts, so that's not the issue.
Thank you.
You can try to load the desired content asynchronously using ajax, doing something like this:
$("a[href='#tabs-1ua']").click(function (event, ui) {
$.ajax({
url: "/Admin/Index",
data: {}
}).done(function (htmlResponse) {
$("#tabs-1ua").html(htmlResponse)
});
});
This loads the result of the action inside the div with id=tabs-1ua.
Maybe this is a simpler approach, let me know if i can be of further help
I load a part of my basketpage inside an accordion div in my header. This works great and shows my basket in a nice dropdown.
The last problem I need to solve with this is to get the buttons in the loaded content to work. Is it possible to write an callback that make these works? Im not sure even what to google for this one..
This is how the buttons is setup in the loaded content:
checkout
Script Im using to load the content:
$('.dcjqg-accordion ul.sub-menu').load('/m4n?seid=etailer-basket div#centerbox.itembox.centerbox');
use the callback function of .load().
$('.dcjqg-accordion ul.sub-menu').load('/m4n?seid=etailer-basket div#centerbox.itembox.centerbox', function() {
$("#_ec_oie2").on("click", function() {
if (UI.pb_boolean(this, 'click')) { }
return false;
});
});
checkout
You need to use a child selector for the event. You can attach an event to the .sub-menu element that will fire on the content loaded in through the ajax. Something like the following could work:
$(".dcjqg-accordion ul.sub-menu").on("click", ".action.actionbasket.checkout", function() {
if( UI.pb_boolean(this, 'click') ) {}
return false;
});
Notice the second parameter to the on method. It is a selector that will be used to look at the target of the click event. I used .action.actionbasket.checkout since that is what is on your a tag.
This code may not work exactly, but this should help get you in the right direction.
Here is the link to the jQuery documentation for the on method: https://api.jquery.com/on/
I think the solution might be obvious, but I cant seem to find it...
this.$modal.on("show.bs.modal", function () {
$("#authModalContent").load("/login/",function(){
$("form").on("submit", function(e){
e.preventDefault();
var data = $("form").serializeArray();
$.post("/login_check",data,function(data){
$("#authModalContent").html(data);
});
});
});
});
data is basically the html content of /login/ route. How to nest this function without creating an infinite loop?
Context: Login page loaded, click submit, backend redirects to /login/ with POST and then that html is transferred to the modal.
FOSUserBundle + symfony2 used
Well, I am gonna answer my own question. You need to find something in your dom that will always stay there and tell him to look up for specific other dynamic elements.
this.$modal.on("show.bs.modal", function () {
$("#authModalContent").load("/login/");
$("#authModalContent").on("submit", "form", function(e){
e.preventDefault();
var data = $("form").serializeArray();
$("#authModalContent").load("/login_check",data);
});
});
Basically my #auModalContentwill always be there and form will be dynamically loaded each time
Greetings,
I would like to know what should I do to make appear a ajax loader...
actually I am calling a function in ajax... everything is going well
here is how it's being done
$('#txtEmail').blur(function()
{
$.post("ajaxAvailability.aspx",{ email:$(this).val() } ,function(data)
{
if(data=='false')
...
Now I would like to have a loader so I done it like this:
$('#loader').ajaxStart(function() {
$(this).show();
}).ajaxStop(function() {
$(this).hide();
});
This should be working? what is happening is that I am getting an exception inside the jquery.js....
-thanks in advance
I usually do this in my code:
$('#txtEmail').blur(function(){
var value = $(this).val();
//display loader image
$("#indicator").html("<img src='PATH/loading.gif' alt='' /> Sending...").show();
$.post(URL,
{ email:value },
function(data) {
$("#indicator").empty().hide();
//...
});
)};
In above code, the animated image will appear inside DOM element with id="indicator". After AJAX request completed, I emptied the container, then hide it. Adjust this according to your page element.
My another code use jQuery blockUI, usually when submitting form, to prevent double submit. Check the web for the usage example.
Greetings, for everyone
The solution for this issue is correct the jquery-1.3.2-vsdoc2.js file
on the ajax function there are f parameter, this should be replaced into callback
